There are some wicked runing small blocks out there. But my 73 dart swinger that weighed 3520 with me in it, ran 10.62 at 126 in the 1/4 on 93 pump gas. I had a 0.030 over 440 with about 10.9 compression. Installing 2 750 Holley DP and letting my friend drive it. He weighs about 100 pounds lighter than me at the time. The car ran a bunch of 10.49 in the 1/4. So I'm saying this you can run pretty fast on pump gas now days
